The reduction of tetrazolium salts by plant mitochondria

Histochemie, 1968
Data has been obtained concerning the reduction of tetrazolium salts by mitochondria isolated from Jerusalem artichoke tubers with succinate as the substrate using a direct recording spectrophotometric method of assay. ATP was found to increase the rate of reduction of the tetrazolium salts, this being independent of the effect ATP had on the rate of ...

Tetrazolium salts and formazans

2020
Tetrazolium salts discussed here are of the 2-H type, and contain one or more five-membered heterocyclic rings, each of which carries a delocalized positive charge. Such a tetrazolium compound may be represented by a pair of Kekule forms. Tetrazolium salts can be reduced to formazans by a variety of mild reductants, including those of enzyme-catalyzed ...

Reduction of tetrazolium salts by malarial parasites

Experimental Parasitology, 1968
Abstract Free and intraerythrocytic forms of Plasmodium berghei and P. knowlesi reduced tetrazolium salts to their colored formazans when these cells were incubated with TZ under anaerobic conditions. Mepacrine hydrochloride incubated with P. berghei in vitro inhibited tetrazolium reduction.

On the oxygen-sensitivity of various tetrazolium salts

Histochemie, 1970
1. Eight different tetrazolium salts have been chemically reduced with NADPH and PMS1 under oxygenated and oxygen-free conditions. 2. PMS has been shown to be able to remove all of the hydrogen from NADPH very rapidly, and to transfer all of this hydrogen onto tetrazolium salts, under suitable atmospheric conditions. 3.

Reduction of Tetrazolium Salt

Nature, 1954
SOME two hundred papers dealing with the chemistry of triphenyltetrazolium chloride and its use as a redox-indicator have been reviewed by Ried1 and Smith2. In spite of its wide use in biology, up to the present little is known about its reducing mechanism, the influence of experimental conditions on it, on its redox-potential, etc., and therefore the ...

Viability and Tetrazolium Salt in Ascites Tumours

Nature, 1960
THE use of tetrazolium salts in experimental and human pathology is valuable if the materials being examined are vital organs or tissues, for degenerating or dead tissue loses the ability to reduce tetrazolium salts1. The formation of formazan is widely used for the determination of general metabolism2.

The Chemistry of Tetrazolium Salts

2002
Tetrazolium salts are an important class of leuco dyes that have found a wide range of applications. They are unique among the synthetic leuco dyes in that the colored form of the dye is the reduced form rather than the oxidized form. There are at least three extensive reviews on tetrazolium salts and the corresponding formazan dyes and one textbook ...

Radiolysis of solutions of tetrazolium salts

Russian Chemical Reviews, 1998
Published data on radiolysis of liquid (mainly aqueous, water–alcohol and alcoholic) and solid [mainly in poly(vinyl alcohol)] solutions of tetrazolium salts are generalised. The mechanism of radiolytic transformations of these compounds is discussed. Their application in dosimetry of ionising radiation is considered in detail.

Mechanism of the Reduction of Tetrazolium Salts

Nature, 1955
INVESTIGATIONS undertaken since our previous publication1 seem to permit of the following additional statements on the reduction and photochemical properties, respectively, of tetrazolium salts used as dehydrogenase indicators.
